Sermorelin Dosage Calculator: Find Your Ideal Dose for Optimal Results

What Makes Sermorelin Different From Other Peptides?

Sermorelin is a 29-amino acid peptide that works by stimulating your pituitary gland to produce and release growth hormone naturally. Unlike synthetic HGH injections that bypass your body's regulatory systems, sermorelin supports your body's own hormone production cycle.

This distinction matters for dosing because sermorelin works with your natural rhythms rather than overriding them. Your pituitary gland still controls the release, which means your body maintains its feedback mechanisms and reduces the risk of excess growth hormone levels.

Why this affects your dose: Because sermorelin stimulates natural production rather than replacing hormones directly, the dosing window is more forgiving than direct HGH therapy. However, getting the dose right still matters for optimal results.

Sermorelin Dosage Ranges: What the Research Shows

Clinical protocols and practitioner experience suggest the following general dosage ranges:

Starting Doses by Goal

Dosing Considerations by Demographics

For women: Many practitioners start female patients at 100-200 mcg daily due to differences in body composition and hormone sensitivity. The dose may be adjusted upward based on lab results and symptom response.

For men: Starting doses typically range from 200-300 mcg daily, with potential increases to 400-500 mcg based on individual response and treatment goals.

For older adults (55+): Lower starting doses of 100-200 mcg are often recommended, with gradual increases as tolerated. Age-related changes in pituitary function may affect response.

How to Calculate Your Sermorelin Dose

Calculating your dose requires understanding the relationship between your vial concentration, syringe units, and desired mcg dose.

Step 1: Determine Your Vial Concentration

After reconstitution, your concentration depends on how much bacteriostatic water you add:

Step 2: Calculate Units on Your Syringe

Using a standard U-100 insulin syringe (100 units = 1 ml):

Formula: Units to draw = (Desired dose in mcg ÷ Concentration in mcg/ml) × 100

Example calculations for a 2 mg/ml (2000 mcg/ml) concentration:

Example calculations for a 3 mg/ml (3000 mcg/ml) concentration:

Reconstitution: Getting It Right

Proper mixing ensures your sermorelin maintains its potency and delivers accurate doses.

What You Need

• Sermorelin lyophilized powder vial
• Bacteriostatic water (not sterile water or saline)
• Sterile syringes (one for mixing, separate ones for injections)
• Alcohol swabs
• Clean, flat work surface

Reconstitution Process

1. Prepare your workspace: Clean your surface and wash your hands thoroughly. Gather all supplies before starting.

2. Clean the vial tops: Wipe the rubber stoppers of both the sermorelin vial and bacteriostatic water with alcohol swabs. Allow to air dry.

3. Draw the bacteriostatic water: Using a sterile syringe, draw your calculated amount of bacteriostatic water. Most protocols use 3-6 ml depending on vial size and desired concentration.

4. Add water to the sermorelin vial: Insert the needle into the sermorelin vial at an angle, aiming the stream at the glass wall rather than directly onto the powder. Add water slowly.

5. Allow to dissolve: Let the vial sit for 1-2 minutes. The powder should dissolve on its own. If needed, gently roll the vial between your palms. Never shake the vial as this can damage the peptide structure.

6. Inspect the solution: The reconstituted sermorelin should be clear and colorless. Do not use if cloudy, discolored, or containing visible particles.

Storage After Reconstitution

• Refrigerate at 36-46°F (2-8°C)
• Keep away from light
• Use within 28-30 days of reconstitution
• Never freeze reconstituted sermorelin
• The peptide remains stable at room temperature for up to 72 hours if needed during travel

Administration Protocol

Timing Your Injection

Sermorelin is most effective when administered at bedtime, approximately 30-60 minutes before sleep. This timing aligns with your body's natural growth hormone release pattern, which peaks during deep sleep.

Timing guidelines:

• Inject on an empty stomach (at least 2 hours after eating)
• Avoid eating for 30 minutes after injection
• Maintain consistent timing each night
• If you miss a dose, take it when you remember unless it's close to your next scheduled dose

Injection Technique

Sermorelin is administered via subcutaneous injection into the fatty tissue just beneath the skin.

Preferred injection sites:

• Abdomen (2 inches away from navel)
• Front or outer thigh
• Back of upper arm

Site rotation: Alternate injection sites to prevent tissue irritation, scarring, or lipodystrophy. Many patients rotate between left and right sides of the abdomen on alternating days.

Weekly Schedule Options

Standard Protocol (5 days on, 2 days off): This is the most common schedule. Inject Sunday through Thursday, rest Friday and Saturday. The break helps prevent receptor desensitization.

Daily Protocol (7 days per week): Some practitioners prescribe daily injections for the initial 4-6 weeks, then transition to 5 days per week for maintenance.

Individualized Protocol: Your provider may adjust your schedule based on your response, lab results, and treatment goals.

Treatment Phases and Cycle Length

Phase 1: Initial Loading (Weeks 1-4)

During the first month, your body is adjusting to sermorelin therapy. Most patients start noticing improved sleep quality within the first 2 weeks.

What to expect:

• Improved sleep depth and quality
• Subtle energy improvements
• Possible injection site reactions (mild, temporary)

Phase 2: Optimization (Months 2-3)

Benefits become more noticeable as growth hormone levels optimize.

What to expect:

• Increased energy and mental clarity
• Improved recovery from exercise
• Enhanced skin quality
• Early body composition changes

Phase 3: Maintenance (Months 4-6+)

Full benefits typically manifest by month 3-4 and continue with consistent use.

What to expect:

• Continued body composition improvements
• Sustained energy and sleep benefits
• Potential dose adjustments based on lab work

Cycle Duration

Most treatment protocols run for 3-6 months continuously. After this period, your provider may recommend:

• A 1-2 month break before resuming
• Continued treatment with periodic monitoring
• Dose adjustments based on your response

Long-term use beyond 6 months should include periodic lab testing (IGF-1 levels, metabolic panel) and provider evaluation.

Signs Your Dose May Need Adjustment

Signs Your Dose May Be Too Low

• No improvement in sleep quality after 3-4 weeks
• Minimal energy changes after 6-8 weeks
• Lab work shows IGF-1 levels unchanged from baseline

Signs Your Dose May Be Too High

• Water retention (puffy hands, ankles, face)
• Tingling or numbness in extremities
• Joint stiffness or discomfort
• Headaches, particularly in the morning
• Carpal tunnel-like symptoms

If you experience these symptoms, contact your provider. Dose reduction typically resolves these effects within a few days.

Factors That Affect Your Response

Lifestyle Factors

Sleep: Sermorelin works best when you're getting adequate sleep (7-9 hours). Poor sleep habits can diminish results.

Diet: A protein-adequate diet supports the anabolic effects of improved growth hormone levels. Avoid eating close to injection time.

Exercise: Regular physical activity, particularly resistance training, can enhance sermorelin's effects on body composition.

Stress: Chronic stress and elevated cortisol can interfere with growth hormone signaling.

Medical Factors

Age: Older individuals may require dose adjustments and may experience more gradual results.

Body composition: Those with higher body fat percentages may need different dosing considerations.

Other medications: Certain medications, including glucocorticoids and thyroid hormones, can interact with sermorelin.

Underlying conditions: Diabetes, thyroid disorders, and other hormonal conditions require careful monitoring during therapy.
